(54) HYBRID MINIATURE CIRCUIT BREAKER


(57) A hybrid circuit breaker includes a primary trip/isolation relay component and a primary trip/isolation relay component driver coupled to the primary trip/isolation relay component and structured to interrupt current from flowing to the load in an event of fault; a sensing mechanism structured to sense at least current, voltage, and power flowing to the load; a metrology component coupled to the sensing mechanism and structured to monitor and measure at least the current, voltage and power; a controller structured to detect the event of fault based on data received from the sensing mechanism and the metrology component and communicate with a user device; and a hybrid secondary switching device coupled to the controller and the primary trip/isolation relay component, the hybrid secondary switch device including secondary contacts, a miniaturized electromechanical relay and a power electronics circuit connected in parallel with the miniaturized electromechanical relay.
